Thermocouple

DESCRIPTION A thermocouple is a sensor for measuring temperature. It consists of two dissimilar metals, joined together at one end, which produce a small unique voltage at a given temperature. This voltage is measured and interpreted by a thermocouple thermometer. THERMOCOUPLE TYPES Thermocouples are available in different combinations of metals or calibrations. The four most common calibrations are J, K, T and E. Each calibration has a different temperature range and environment, although the maximum temperature varies with the diameter of the wire used in the thermocouple. Element              Type      Range Copper/Constantan        (Simplex/Duplex) ...

Thermostats

DESCRIPTION Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes. They are used to control heating and cooling systems. The sensing element is usually a spiral bimetallic strip that coils and uncoils in response to temperature changes because of the differential expansion of the two bonded metals. The switch element is either a set of electrical contacts or a glass-encapsulated mercury switch that controls a low-voltage relay. The relay can actuate a motor starter and igniter for an oil burner, a ...
